* gh-98724: Fix Py_CLEAR() macro side effects (#99100) (#99288)Victor Stinner2022-11-091-0/+87
| | | | | | | | | The Py_CLEAR(), Py_SETREF() and Py_XSETREF() macros now only evaluate their argument once. If an argument has side effects, these side effects are no longer duplicated. Add test_py_clear() and test_py_setref() unit tests to _testcapi. (cherry picked from commit c03e05c2e72f3ea5e797389e7d1042eef85ad37a)

* gh-98740: Fix validation of conditional expressions in RE (GH-98764)Miss Islington (bot)2022-11-031-27/+29
| | | | | | | | | | | | | | In very rare circumstances the JUMP opcode could be confused with the argument of the opcode in the "then" part which doesn't end with the JUMP opcode. This led to incorrect detection of the final JUMP opcode and incorrect calculation of the size of the subexpression. NOTE: Changed return value of functions _validate_inner() and _validate_charset() in Modules/_sre/sre.c. Now they return 0 on success, -1 on failure, and 1 if the last op is JUMP (which usually is a failure). Previously they returned 1 on success and 0 on failure.

* [3.11] gh-97897: Prevent os.mkfifo and os.mknod segfaults with macOS 13 SDK ↵Miss Islington (bot)2022-10-061-8/+52
| | | | | | | | | | | | | (GH-97944) (#97969) The macOS 13 SDK includes support for the `mkfifoat` and `mknodat` system calls. Using the `dir_fd` option with either `os.mkfifo` or `os.mknod` could result in a segfault if cpython is built with the macOS 13 SDK but run on an earlier version of macOS. Prevent this by adding runtime support for detection of these system calls ("weaklinking") as is done for other newer syscalls on macOS.

| | | | | | | | | | | | | | Fix the Python path configuration used to initialized sys.path at Python startup. Paths are no longer encoded to UTF-8/strict to avoid encoding errors if it contains surrogate characters (bytes paths are decoded with the surrogateescape error handler). getpath_basename() and getpath_dirname() functions no longer encode the path to UTF-8/strict, but work directly on Unicode strings. These functions now use PyUnicode_FindChar() and PyUnicode_Substring() on the Unicode path, rather than strrchr() on the encoded bytes string.

The script provides several build profiles with configure flags for Emscripten flavors and WASI. The script can detect and use Emscripten SDK and WASI SDK from default locations or env vars. ``configure`` now detects Node arguments and creates HOSTRUNNER arguments for Node 16. It also sets correct arguments for ``wasm64-emscripten``.
